I have worked several F1 events in the States and worked Radio Communication at Vegas. The infrastructure required was massive for sure and the circuit was top notch. The race was only on existing streets and not the temporary bridge if that's what you implied, wasn't sure. Top speed past Bellagio was 212 mph. The circuit will not be repaved next year but locals will never like the event. F1 has a ten year agreement so we'll see. And yes it is all about the Benjamins...but isn't it always?
